It is well known that, although two materials are at the same temperature, one may feel cooler to the touch than the other. Consider thick plates of copper and glass, each at an initial temperature of 300 K. Assuming your finger to be at an initial temperature of 310 K and to have thermophysical properties of ρ = 1000 kg/m3, c = 4180 J/kg ∙ K, and k = 0.625 W/m ∙ K, determine whether the copper or the glass will feel cooler to the touch.
